The indentations 28a are prev-meson the side of the stamping opposite to that from which the-fiangeportionszllb extend, and the stampings 29 are mounted on the reachhmembersl to cause their indentured surfacestobemelatively confronting.

vThe said stampings 20 are carried by the reach members. and afford suitably. indentured. facing surfaces therefor. .In Fig. 5. a generally U-shaped clamp element 5. is. shown, t rme .fmm. a piece of fiat zsheet lsteelhmaterial andflbent, into the ii-151. sa d mn element. hav n a pa r-9 pe ionated, re1atiye1y par ll l armsnfi, and? .1, and h v n fl neeiaw por ons, 8 en 9 nrei ctinemwe dl i om the t an be tomnqrti nsso th @Qp .2 1-

The upper end of the post therefor may be projected upwardly between the jaw edges and said web while rotated to present the notch I3 foremost, that is, toward the ends of the arms 6 and 7.

With a pair of the shallow channel-shaped members each respectively positioned on a diiferent one of the reach members 2, and with their indentured surfaces Zlla disposed in relatively confronting relationship, the member 5, with the post 12 frictionally pendantly supported thereby, is interposed between the opposing in dentured surfaces of the stampings 2b.

The stem bolt I6 is then advanced through the rectangular opening 2a of the remotely disposed first reach member 2, through the aperture 22 of the stamping 20 which is afiixed thereto, then through the aligned apertures 5a of the clamp 5, and through aligned apertures of the other stamping 2!! which is affixed to the second reach member 2, and through the aperture thereof, the nut 26a being then screw-threaded onto the stem M of the bolt it which is shown in Fig. 8.

Thus the head of the bolt i6 is disposed at one side of the first reach member 2 and the nut 28a is disposed at the other side of the other reach member as best shown in Fig. 2. In such case the arms 6 and 1 together with their respective jaws 8 and 9 are projected to considerable inwardly directed pressure when the nut 26a is turned on to the stem it of the bolt. The squared shank lea of the bolt being fitted within the rectangular aperture 2a of the first reach member prevents the bolt from turning during the clamping rotational movement of the nut 26a. Such clamping effectuates inwardly directed pressure on the clamping jaws 8 and 9 with the result that the frictional grip exercised by the jaws 8 and 9 and also the surface ll of the clamping member is intensified.

As an important additional feature of improvement the arcuate notch I3 is positioned with its arcuate surface concentric with the aligned apertures 5a of the clamp 5 so that when the bolt stem Hi is projected through the apertures 5a the arcuate surface of the notch l3 will be subject to engagement by the bolt stem M to thus key the bolt M, clamp 5, and post 52 together, thus preventing up-and-down sliding of the clamp channel on the post.

Therefore, frictional clamping engagement of the clamp with the post is not mainly relied upon to prevent longitudinal displacement of the clamp with respect to the upper portion of the post which clamp is relied upon more particularly to hold the cycle saddle from tilting.

It will be well understood from the present practice in this art that the radially extending indentured grooves of the clamp and 29a of the reach member facings 28 are provided for the purpose of preventing tilting of the cycle seat from a desired position of adjustment, and that also by unscrewing the nut l5 to loosen the clamp, that the seat can then be tilted to the desired tilting adjustment position and retained in such position by retightening the nut, and that the keying effect of the bolt stem portion which is projected within the notch I3 of the post ID will effectually prevent the up and down sliding of the assembled seat and clamp mechanism on the post l2 during the period of making the tilting adjustment or subsequent readjustment.

Having thus described my invention in a single embodiment, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described but without departing from the spirit of my invention.

I claim:

1. A cycle saddle post and clamp assembly comprising in combination with a pair of laterally spaced, longitudinally extending reach bars having transversely aligned apertures, a pair of indentured apertured members each carried by one of said reach bars, a substantially U- shaped clamp bent from a piece of flat sheet steel material and aifording a web and a pair of intermediately apertured side arms, said arms positioned between, while extending longitudinally of, said bars, the outer surface of each arm disposed fiatwise in contiguous relation to an inner surface portion of a different indentured member, a substantially upright post having a transverse notch on a side of its upper end portion, said upper portion adapted to be disposed between said arms and its unnotched surface portions to be concurrently engaged with inner surface portions of said arms and an inner surface portion of said web, and said notch being presented towards the space between the ends of the arms, and bolt means comprising a stem portion adapted to be projected successively through a bar aperture, said indentured member and clamp arm apertures, and the other bar aperture and concurrently to pass through and be embraced by said post notch, and said bolt means adapted for adjustment to inwardly compress said bars against the indentured members, to inwardly compress the side portions of the clamp arms against the sides of the post.
